Because They Klingon...?

Maybe Captain Picard should ask the Enterprise's leading kayaking expert, Chief Miles O'Brien. After moving on to Deep Space Nine, he liked to relax by whitewater kayaking in Quark's holosuites. He dislocated his shoulder a number of times and Quark eventually told him that the kayaking program had "gone missing" to prevent further injuries. I guess no more paddling where no one has paddled before for him.
